To solve this question, the user needs to understand the different SQL operators and how they work. The user must also know how to use these operators in a SQL statement to perform a specific task.

Now, let's go through each option and explain whether it can be used to substitute the 'IN' operator:

A. ALL: The ALL operator is used to compare a value to all values in another set of values. It cannot be used to substitute the 'IN' operator. Therefore, option A is incorrect.

B. BETWEEN...AND: The BETWEEN...AND operator is used to select values within a given range. It cannot be used to substitute the 'IN' operator. Therefore, option B is incorrect.

C. LIKE: The LIKE operator is used to compare a value to similar values using wildcard characters. It cannot be used to substitute the 'IN' operator. Therefore, option C is incorrect.

D. OR: The OR operator is used to combine multiple conditions in a WHERE clause. It can be used to substitute the 'IN' operator by specifying each value as a separate condition joined by the OR operator. Therefore, option D is correct.

The Answer is: D
